Identify the slope and y-intercept of the line whose equation is given. write the y-intercept as an ordered pair. y = negative 2

PSYCHO15rus [73]

The line having the equation, y = -2x + 5, has a slope = -2, and y-intercept = (0, 5). Thus, <u>option A</u> is the best choice.

The slope of a line is the tangent of the angle that the line makes with the positive side of the x-axis.

The y-intercept of a line is the point at which the line intersects the y-axis.

The standard form of a line is <u>y = mx + b</u>, where m represents the slope of the line, and b represents its y-intercept.

In the question, we are asked to identify the slope and the y-intercept of the line whose equation is y = -2x + 5.

Comparing the given equation of the line, y = -2x + 5, with the standard equation of a line, y = mx + b, we can say that,

m = -2, and b = 5.

Representing b as an ordered pair, we get (0, 5), as b represents the y-intercept which is a point on the y-axis, where the x-coordinate is always equal to zero.

Thus, we get the slope = -2, and the y-intercept = (0, 5).

The option representing the answer is <u>option A</u>.

The American Heart Association is about to conduct an anti-smoking campaign and wants to know the fraction of Americans over 46

Luba_88 [7]

Answer:

1.) .800

2.).779 to .821

Step-by-step explanation:

We must assume that the sample that we are given to work with is representative of the population, in which case we just need to find the proportion of people in the sample who don't smoke. This is $\frac{1738}{2172}$ = .8002, or .800 rounded to three decimal places.

Part 2 will build off the answer in step 1. The middle of the confidence interval will be the estimate gained from the sample, or .800. The critical value of 98% equals 2.326 when using the normal model. The standard deviation can be calculated using the formula $\sqrt{\frac{(proportion)(1-proportion)}{n} }$ . Plugging in the numbers you get $\sqrt{\frac{(.8)(.2)}{2172} }$ = .009.

This means the confidence interval is .800±.021
